Description
Technical field:
A kind of rotating speed instrument relates to instrument field, has central microprocessor and performs mathematical calculations, and the high-brightness LED numeral of accurately counting according to the frequency pulse input signal shows measured value.
Background technology:
Present rotating speed instrument mainly is made up of fixed support, mainboard, tablet, display board, supports the single pulse signal input, and circuit is fairly simple, can finish simple measurement, for nonlinear properties and multiple pulse signal, can't discern.
The utility model content:
The purpose of this utility model is to have multiple pulse signal input function and can handle simultaneously linearity or nonlinear properties in order to address the aforementioned drawbacks, to provide, and grasps easily, and is multiple functional, the rotating speed instrument that versatility is good.Its technical solution is as follows:
A kind of rotating speed instrument mainly is made up of mainboard, tablet, display board, frequency signal input end and supporting element and casing, it is characterized in that: frequency signal input end and tablet are welded to each other with soft arranging wire, tablet is arranged with the welding hole on the mainboard by contact pin row and is in 90 degree welding simultaneously, mainboard becomes an angle of 90 degrees to fix with frequency signal input end by cross bar and sieve silk again, the another side of display board and mainboard is in an angle of 90 degrees by pad or contact pin and welds together, complete machine cover upper casing, display board sticks facial mask; Mainboard is characterized in that: mainboard also comprises CPU processor, storer, comparer, logical gate operations device, power supply unit, is interconnected with one another and is welded on the mainboard; Tablet is characterized in that: tablet includes two in the potentiometer that regulating frequency signal input voltage scope uses, frequency signal sample circuit unit; Display board is characterized in that: display board comprise button several, show seven segment digital tubes that numerical value uses, light emitting diode several, interconnect and be welded on the display board.The frequency signal of various high frequencies or low frequency is delivered to tablet by signal input part, operating personnel make the various height of input by the voltage magnitude of regulating the potentiometer regulating frequency signal input on the tablet, low-frequency signals can be crossed tablet smoothly, simultaneously tablet carries out processing and amplifying with the signal that collects and delivers to the logical gate operations device and carry out computing, and after comparer selects finally to deliver to the CPU processor, the CPU processor carries out the computing operation result that the user is required and deposits in the storer, data in the storer are called on the display board again, display board is converted into tachometer value by seven segment digital tubes with concrete frequency values and is shown to the user, measures the purpose that shows to reach.
The utility model has the advantages that and to receive the various frequency signals in the different high and low frequency scopes and carry out processes and displays, because it adopts optimization of CPU processor and comparer gating, can also correct nonlinear properties simultaneously, make the rotating speed instrument intelligent more.
